  1. Question 1

    Q1. A 20 kHz AC signal is passed through a capacitor with a capacitance of 10 μF. What is the reactance of the capacitor?

    • A) 50 Ω
    • B) 200 Ω
    • C) 1000 Ω
    • D) 5000 Ω

    Answer: 200 Ω

    Explanation: The reactance is given by Xc = 1 / (2πfC), so it's 200 Ω, not 50 Ω, 1000 Ω, or 5000 Ω.
